PAKISJAYA, INDONESIA (Reuters) – An Indonesian plane with 1
The Flight Lion Air JT610, an almost new Boeing 737 MAX 8, lost contact with the ground officers 13 minutes after takeoff and crashed about 15 km off the coast.
Indonesia is one of the fastest growing aviation markets in the world, although its safety record is patchy. If all had died on board, the crash would be the second worst aircraft in the country since 1997, industry experts said.
"We do not yet know if there are any survivors," said Muhmad Syaugi, head of search and rescue news conference, adding that no emergency signal had been received from the aircraft's emergency transmitter.
"We hope we pray, but we can not confirm."
Items such as handheld switches and lifejackets were found in waters over 30 feet. At a height of 35 meters (98 to 115 feet) near the aircraft, a Boeing 737 MAX 8, he lost contact.
"We're already there, our ships, our helicopter hovering over the waters." Said Syaugi. "We try to dive to find the wreck."
Ambulances were stationed in Karawang on the coast east of Jakarta, and police were preparing dinghies, Reuters told a reporter. Fishing boats were used to help with the search.
At least 23 government officials were aboard the plane, which an air traffic control spokesman had said returned shortly before contact was lost.
Edward Sirait, managing director of Lion Air Group, told reporters the plane had a technical problem on a flight from the holiday island of Bali to Jakarta, but it was "resolved after the procedure".
Sriait declined to specify the nature of the problem, but said nothing else aircraft of this model had the same problem. Lion has used eleven Boeing 737 Max 8 engines and plan not to ground the rest.
The accident is the first to report the widespread Boeing 737 MAX, an updated, fuel-efficient version of the manufacturer's longevity workhorse.
Private ownership Lion Air said that the aircraft had been in service since August, was capable of flight, with its pilot and copilot, who had accumulated 11,000 flight hours together.
The Head of the Indonesian Road Safety Committee said he could not confirm the cause of the accident, which would have to wait until the aircraft's black boxes were restored, as the cockpit voice recorder and the data escape recorder are known.
"The plane is so modern it transmits data from the plane, and we will check that, but the most important thing is the black box," said Soerjanto Tjahjono.
Security experts say that almost all accidents are caused by a combination of factors and rarely have one individual identi
The weather was clear, Tjahjono said.
President Joko Widodo told a press conference that the authorities focused on the search and rescue, and he called for the prayers and support of the country.
SOMETHING AMISS  Efforts to find the wreck and find the black boxes are a major challenge for investigators in Indonesia, where an AirAsia Airbus crashed in Java Lake in December 2015.
Under international rules, the US National Transportation Safety Board will automatically assist with the investigation of the crash on Monday, supported by Boeing technical consultants and the American-French engine manufacturer CFM International, General Electric and Safran.
Boeing was deeply saddened by the loss, it said in a statement, and was ready to provide technical assistance for the investigation.
